35. Twe towers AB and CD are situated at a distance \( d \) apart. AB is 20 m high and CD is 30 m high from the ground. An object of mass \( m \) is thrown from the top of \( A B \) horizontally with a velocity of \( 10 \mathrm{~ms}^{-1} \) towards \( C D \). Simultaneously, another object of mass 2 m is thrown from the top of CD at an angle of \( 60^{\circ} \) to the horizontal towards AB with same magnitude of initial velocity as that of the object. The two objects move in the same vertical plane, collide in mid air and stick to each other.
(i) Calculate the distance \( d \) between the towers and
(ii) find the position where the objects hit the ground.
